Landlord & property accountant in West London

Know the real rental profit, the tax building up, and what changes when you sell.

SV&Co helps landlords and property owners across Southall, Ealing, Hayes, Wembley and wider West London with rental accounts, Self Assessment, MTD, property expenses, jointly owned property, Capital Gains Tax and property-company questions.

Rental income, taxable profit and cash in the bank are three different numbers.Mortgage payments, repairs, improvements, tax and MTD rules can all change the answer. We start by separating the numbers properly.

Rental profit

HMRC taxes the property profit, not simply the rent received.

Rental profit starts with property income and deducts allowable running expenses. Residential finance costs for an individual landlord are then dealt with separately through the finance-cost tax-reduction rules.

Example: one rental property

  • Rent received: £24,000
  • Agent, insurance and repairs: £6,000
  • Property profit before residential finance-cost rules: £18,000
  • Mortgage interest: £8,000

An individual residential landlord does not simply reduce the £18,000 to £10,000 by deducting the mortgage interest. Instead, HMRC's basic-rate finance-cost tax reduction is considered separately.

The £1,000 property allowance

Individuals can have a property allowance of up to £1,000 a year. Depending on the circumstances, it can sometimes be used instead of actual property expenses.

If gross property income is £1,000 or less, it may be exempt, subject to the exclusions in the rules. Where actual expenses are larger than the allowance, claiming the actual expenses may be more sensible.

Property expenses

A repair and an improvement can look similar on the bank statement but receive different tax treatment.

HMRC allows normal day-to-day property-business expenses, but capital improvements are not simply deducted from rental income.

Letting & professional costs

Letting-agent fees, certain legal fees, accountancy fees and similar property-management costs can commonly be allowable where they relate to the rental business.

Insurance & services

Buildings/content insurance, service charges, cleaning, gardening, utilities and Council Tax paid by the landlord can be relevant running expenses.

Repairs

Maintenance and repairs can normally be revenue expenses where they restore rather than improve the property. Replacing an old item with a modern equivalent does not automatically turn a repair into an improvement.

Improvements

An extension, significant enhancement or capital improvement is usually not deducted from annual rental profit. Some capital expenditure may instead become relevant when calculating a future capital gain.

Domestic items

Replacement furniture, furnishings, appliances and kitchenware in qualifying residential lettings can fall within separate Replacement of Domestic Items Relief rules.

Mortgage capital

Repaying the capital borrowed to buy the property is not a rental expense. Interest and other finance costs follow the separate residential landlord rules for individuals.

Mortgage interest

For an individual residential landlord, interest relief is not a normal expense deduction.

Since 2020/21, residential property finance costs for individuals are restricted to a basic-rate Income Tax reduction. Companies are outside this individual-landlord restriction and generally deal with finance costs under company tax rules.

Why this matters

A landlord can have modest cash profit after paying the mortgage but a much higher taxable property profit before the finance-cost tax reduction. The effect is particularly important for higher-rate taxpayers.

Making Tax Digital for landlords

MTD uses gross qualifying income before expenses.

For MTD for Income Tax, HMRC combines qualifying personal self-employment and property income. The first cohort entered MTD from 6 April 2026 where qualifying income on the 2024/25 return was over £50,000.

£30,000Over this on 2025/26 return → April 2027.
£20,000Over this on 2026/27 return → April 2028.
Digital recordsIncome and expenses must be recorded in compatible software where MTD applies.
Example

£28,000 self-employment income plus £25,000 gross property income gives £53,000 qualifying income before expenses. The sources can combine even though the activities are completely different.

Ownership

Personal name, joint ownership or limited company can produce very different outcomes.

There is no universal “best” property structure. The right answer depends on financing, tax rate, whether profits are reinvested or withdrawn, future sales, ownership with a spouse/partner and long-term plans.

Personally owned

Rental profit is part of the individual's Income Tax position. Residential finance-cost relief is restricted to the basic-rate tax-reduction mechanism. A future property sale can create personal CGT.

Jointly owned

For spouses and civil partners living together, jointly held property income is normally taxed 50:50. A valid Form 17 can apply where genuine beneficial ownership and income entitlement are unequal and the required conditions are met.

Limited company

The company is a separate legal taxpayer. Finance costs, Corporation Tax, extraction of profits, mortgages, SDLT and future sale/extraction strategy all need considering together. Moving an existing personally owned property into a company is not the same as buying the next property through a company.

Rent a Room

Taking in a lodger can follow a different tax regime.

The Rent a Room Scheme can allow up to £7,500 a year of qualifying receipts tax-free where furnished accommodation is let in your only or main home. The threshold is normally halved where the income is shared with another person.

Selling a rental property

The CGT deadline can arrive long before the next Self Assessment deadline.

For taxable gains on UK residential property, an individual may need to report and pay Capital Gains Tax within 60 days of completion. The current individual CGT rates are generally 18% and 24%, depending on how much of the gain falls within the unused basic-rate band.

2026/27 Annual Exempt Amount

The current CGT annual exempt amount for most individuals is £3,000. It is one annual exemption across gains, not a separate £3,000 allowance for each property.

Landlord tax FAQs

Questions we regularly need to separate properly.

Does mortgage interest reduce my rental profit?

For an individual residential landlord, finance costs are generally dealt with through the basic-rate tax-reduction rules rather than simply deducted from rental profit. Companies follow different rules.

Do I add my rental income to my sole-trader income for MTD?

Yes, relevant personal self-employment and property income can combine when HMRC tests MTD qualifying income. The test uses gross qualifying income before expenses.

Can I claim the cost of a new kitchen?

It depends whether the work is a repair/replacement or a capital improvement. Restoring an existing asset can be revenue in nature, while significant improvement or enhancement can be capital. The actual work and old/new specification matter.

Should I put my rental property into a limited company?

Not automatically. A company can change the tax treatment of finance costs and retained profits, but transferring an existing property can create CGT, SDLT, refinancing and legal issues. The long-term plan matters.

How quickly must I report a residential-property capital gain?

Where UK residential-property CGT is reportable, the current rule generally requires reporting and payment within 60 days of completion.

Can my spouse and I simply choose any rental-income split?

No. Spouses/civil partners living together are normally taxed 50:50 on jointly held property income. Form 17 can apply only where the genuine beneficial ownership and income entitlement are unequal and the conditions are satisfied.
